車両用自動変速機の安全装置。By intermittently controlling the clutch group 1 provided for each speed stage of the transmission via the shift control valve 2 provided for each clutch, the shift control of the transmission is performed. Pilot circuit 4 that supplies hepilot pressure
A safety valve 9 that operates based on the pressure difference before and after the throttle 6 is installed in the pipe 7 connected to the input side of the throttle 6, and the pilot pressure flowing into the pipe 7 when the engine is started causes the valve to shut off at the shutoff position 11. An auxiliary valve 11 is provided which is switched to the communication position 112 from □ and returns to the cutoff position 111 with the passage of time.
This is a safety device for an automatic transmission for a vehicle, in which pressure is introduced into the return spring 9a side of a safety valve 9.
